DAVIT.

Specification of Letters Patent.

Patented July 11, 1911.

Application filed November 27, 1909. Serial No. 530,283.

T 0 all whom it may concern:

Be it known that I, SIMON Mon, engineer, citizen of Norway, residing atthe city of I-Iarstad, Norway, have invented new and useful Improvementsin Davits, of which the following is a specification.

The present invention relates to that kind of davits which swing inplanes perpendicular to the longitudinal direction of the vessel and theouter and inner part of which are bent in relation to each other to forman angle less than 90 degrees, so that the boat on the deck is locatedabove the said inner part and below or outside the outer part of thedavit. The latter is by means of tackle attached to a stand arrangedclosely inside the davit.

The invention is illustrated in the accom panying drawing, in whichFigure 1 is an elevation showing a portion of a vessel with the davitand life-boat in normal resting position. Fig. 2 is a similar view, inwhich the boat is shown as swung outboard. Fig. 3 is a plan View.

Each davit arm Z) which may be made of round iron, angle iron or otherrolled iron, is pivoted at 0 at the outer edge of the deck. From thispoint 0 it passes beneath the boat resting on chocks h and then it bendsupward at the inner side of the boat and also outward up to suitabledavit height directly above the middle line of the boat.

The upper head of the davit b is engaged-by the fixed block -f of theboat tackle, which is drawn tight and locked. The fixed block (Z- ofeach davit tackle engages the upper head of the vertical stand a and therunning block engages the outwardly directed upper part of the davitneart-he inner end of said part, 2'. 6. near the point at which the bendto the inner bow part begins. The engaging points of the several blocksare so located in relation to each other, that the boat by heaving onthe davit tackles is carried out past a dead position (see Fig. 2), inwhich the vertical plane through the points e passes through the axis ofthe pivots c and in which the moment of torsion caused by the weight ofthe boat changes in direction. hen the davits b by heaving on the davittackles are swung past this dead position, they-during the succeedinglowering on the tackleswill swing the boat farther outboard, as far asthe length of the davits allows it. The swinging is stopped by strongchains g of suitable length having one end attached to a fixed point onthe deck and the other end attached to a suitable point of the davit bowas illustrated in Fig. 2. If desired, a stopping pawl also may bearranged beneath each davit at its lower end for preventing it fromcoming out of position during the lowering of the boat in case ofrolling.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is In combination, a ship; bow-shaped davitsswinging in planes perpendicular to the longitudinal direction of thevessel and each having an inner and outer part bent in relation to eachother to form an angle less than 90 degrees, the end of the inner orlower part being pivotally connected to the deck of a ship and the endof the outer or upper part being pivotally connected with a tackleadapted to carry a boat; a fixed upright stand arranged at the rear ofeach davit; a tackle for each davit, the upper fixed block of the tacklebeing pivotally con nected to the upper end of the stand, the lowerrunning block of the tackle being pivotally connected with a loop at anintermediate point on the upper part of the davit, said loop beinglocated beneath the line between the attaching pointof the fixed blockand the pivoting point of the davit, said loop being further so locatedthat when the attaching point of the running block by heaving on thedavit tackle has been raised into the said line the vertical linethrough the upper carrying point (e) of the davit is outside thevertical line through the pivoting point of the davit, all for thepurpose, that the boat may easily be lowered by first heaving and thenlowering on the davit tackles.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
